Colleagues use Java to do a crawl of any page title, because the HTML of any page in the head of the meta-specified charset a variety of, such as commonly used utf-8,gbk,gb2312.Write their own code processing, in a short time, found a variety of situations too difficult to think about, always crawl garbled. Challenges: There may also be meta or meta, even if there is meta may also be uppercase or lowercase, even if the case is done with white space ch

In the previous "OpenSSL and keystore instruction small set," said the recent study of SSL encryption, will give a small example of Java. Copying a piece of code that can run to production is very irresponsible, but a small example can lead us to a quick glimpse of the nature of things. Rome was not built in a day.This article will give a small

amount of space memory. When the request arrives, the buffer pool assigns an idle thread to the request, runs the request into the thread, and processes it. When a predesigned thread is running, a prefab thread is not enough, the thread pool can create a certain number of new threads to handle more requests. When the system compares space, you can also remove a part of the thread that is inactive.The advantage of this is that, on the one hand, the system resource overhead of frequently creating

Java Web user login and logout method example based on Session implementation, javawebsession Preface Cookie: cookie is a client technology. A program sends data of each user to the user's browser in the form of a cookie. When a user uses a browser to access the web resources on the server, the user will carry their own data areas. In this way, the web resources

This way, if you do not log in and access commonuser.jsp directly, you will jump to the login interface. 3, the use of special documents to verify Because many pages have to write validated code, you can put this code in a file to share, need to use the call to share files. The following still takes commonuser.jsp as an example of how to implement the sharing of validation code. Use specialized files to store shared code: Check.jsp Code:

RMI is an RPC framework in the Java language, this article gives the following basic examples:1.

the basic structure of the state pattern:in the main () function, the first implementation is used, and then the second implementation is transferred. When you implement state mode yourself, you encounter a lot of detail, and you have to choose the right implementation method based on your needs , such as whether it is exposed to the calling client and how the state changes. In some cases (such as Swing's LayoutManager), the

Observer object and be able to use it to notify the update. Java provides a built-in way to implement the observer pattern, java.util.Observable and Java.util.Observer interfaces. However, they are not widely used. Because this implementation is too simple, most of the time we do not want the last extended class to simply implement the observer pattern, because Java classes cannot inherit more. The

Many beginners use the Java layout to automatically layout the interface, often encounter problems such as not knowing how to define the area size or the distance between the buttons. In fact, automatic layout can also solve the definition of area size or the distance between buttons, and so on, but not the manual layout so flexible. Let me give you an example. First, build a frame file (application applica

The main function of the servlet is to process the client request and respond, for each request, the Web container creates two objects before the service () is invoked, respectively, HttpServletRequest and HttpServletResponse. where HttpServletRequest encapsulates HTTP request messages, HttpServletResponse encapsulates HTTP response messages. It should be noted that each servlet creates only one instance object during the Web server run, but each requ
